MiFare IC secures the future of contactless smart city services

Wed, Jun 03, 2020

Increased security for smart city installations is a feature of the MiFare DESFire EV3 IC, says NXP, claiming it ushers in a new era of security and connectivity for contactless smart city services.

It is the third evolution of NXP’s contactless MiFare DESFire portfolio. It is backwards compatible and offers enhanced performance with a greater operating distance and improved transaction speed. It is also claimed to deliver faster, more secure transactions that are truly contactless, such as paying for parking, accessing offices or campuses and using other essential city services; all touch-free.

The MiFare DESFire EV3 IC can be used by transit agencies, access control providers and system integrators.

The IC hardware and software are certified to Common Criteria EAL 5+, and the IC supports a broad choice of open crypto algorithms. A card-generated MAC helps to securely authenticate transactions, and a new Transaction Timer feature helps mitigate man-in-the-middle attacks making it harder for an attacker to interfere with a transaction. The new Secure Unique NFC (SUN) messaging feature is a secure method for maintaining data confidentiality and integrity. Each time a card, phone or ticket is tapped with the SUN feature enabled, an authentication message and crypto-secure URL are generated and sent to a server for verification, which makes taps unclonable, says NXP.

Support for MiFare DESFire EV3 will be integrated into NXP’s MiFare 2GO cloud service, which manages digitised MiFare product-based credentials and helps streamline mobile integration via NXP’s ecosystem. This will enable smart city services to be seamlessly deployed to NFC-enabled smartphones, wearables and other mobile devices, explains NXP.

For simplified deployment, each MiFare DESFire EV3 IC is pre-configured with keys to enable delegated application management, which supports seamless, over-the-air updates to already deployed smart cards using NFC-enabled smartphones.

NXP’s upcoming MiFare Plus EV2 IC will provide a drop-in replacement for upgrading existing MiFare Plus and MiFare Classic product-based installations to higher security.

Basler introduces embedded vision dev kit for Nvidia Jetson

Wed, Jun 03, 2020

An embedded vision development kit and two add-on camera kits with Basler’s BCON for MIPI interface powered by Nvidia Jetson have been added to the Basler portfolio.

Jetson is the AI platform for autonomous machines and Basler is a preferred partner for Nvidia.

Image processing for today’s AI at the edge applications in robotics, logistics, smart retail, smart factories, and smart cities requires high computing power. The compute and energy efficiency advantages of the Nvidia Jetson platform and Basler’s vision expertise are combined for use in automatic optical inspection and intelligent video analytics.

The Embedded Vision Development Kit, includes the Jetson Nano developer kit, and comes with a Basler dart BCON for MIPI camera with a 13 Mpixel, S-mount lens, an adapter board specifically developed for the Jetson Nano module and accessories. Basler has also integrated a new camera driver and sample reference applications to provide developers with a ready-to-use development package for edge AI use cases.

The two add-on camera kits provide the appropriate vision extension for developers already working with a Jetson Nano processor board. The kits contain either a 5 Mpixel or a 13 Mpixel Basler dart BCON for MIPI camera with S-mount lens, an adapter board and accessories. The required driver packages and the Basler pylon software development kit are available for download.

“With the Basler vision kits for the Jetson Nano, developers get an integrated, easy to use solution for vision-based embedded applications in robotics, manufacturing and industrial IoT,” said Murali Gopalakrishna, head of product management for autonomous machines at Nvidia. “Basler’s ongoing support for the Nvidid Jetson platform brings a wealth of experience in industrial cameras into our partner ecosystem,” he added.

Nvidia Jetson has support for cloud-native technologies, enabling manufacturers of intelligent machines and developers of AI applicationsto build and deploy high-quality, software-defined features on embedded and edge devices targeting robotics, smart cities, healthcare, industrial IoT and more, says Basler. Cloud-native support helps manufacturers and developers implement frequent improvements, improve accuracy, and use the latest features with Jetson-based AI edge devices.

A further add-on camera kit for the recently released Jetson Xavier NX is under development. Additional camera kits for Jetson TX2 and AGX Xavier will follow by Q3/2020, added Basler. The company is also developing an embedded vision system with access to cloud services based on a Jetson Nano due to its specific suitability for AI computing tasks on edge devices. This software solution, which extends embedded vision development kits with machine-learning application software, will also be available by Q3/2020.

Industrial I/O is software-configurable for automation and control

Fri, May 29, 2020

Analog Devices claims to have developed the industry’s first software configurable industrial I/O for building control and industrial automation. The AD74412R and AD74413R are intended for building control and process automation, allowing manufacturers and industrial operators to achieve greater control system flexibility while reducing product complexities.

Traditional control systems require costly and labour-intensive manual configuration, with an array of channel modules, analogue and digital signal converters, and individually wired I/Os to communicate with the machines, instruments, and sensors on the operating floor. The AD74412R and AD74413R enable flexible control systems to be designed with reconfigurable module channels remotely and without requiring extensive re-wiring, explained Analog Devices. This not only increases the speed of implementation, but increases flexibility to make changes without incurring significant cost and system downtime.

The AD74412R and AD74413R will allow manufacturers to adopt industry 4.0, and adapt to changing requirements, driven by changes in consumer behaviour and demand. Flexible systems will react quicker than fixed, large-scaled systems as they can be reconfigured quickly with minimal downtime and capital investment, said Analog Devices. ADI’s software configurable I/O can be used by manufacturers to efficiently implement new projects and achieve more flexible automated control, reduce design and installation costs, as well as commissioning delays.

Software configurable I/O also allows manufacturers to develop a platform that replaces multiple aging fixed function I/O modules or be applied across multiple customer applications where the I/O dynamic changes with each installation.

For systems traditionally reliant on control cabinets with multiple I/O modules and specified wiring for each channel type, users can reduce hardware by installing a single module type programmable from the control room, which decreases logistic, manufacturing and support costs, added ADI.

Software configurable I/O also acts as a bridge to Ethernet-based control networks, as it can further be applied to brownfield installations requiring updates to 10BASE-T1L industrial Ethernet systems. It enables development of standardised, configurable field I/O units capable of translating between installed HART-enabled 4-20mA sensors and actuators and 10BASE-T1L or 100M Fibre backhaul.

Both the AD74412RBCPZ and AD74413RBCPZ are available, both in a 64-lead LFCSP, measuring 9.0 x 9.0mm.
